Bearings • Babbitt Bearings

Babbitt bearings are lined with a soft, white, anti-friction metal that is comprised mainly of copper, antimony, tin and lead. The material, known as Babbitt, is coated over the bore usually to a thickness 0.025 mm to 2.5 mm, and is typically used in integral bearings. Two major families of Babbitt metals are tin based and lead based. Tin-based Babbitt is used for high speed or hard to lubricate bearings, while lead-based Babbitt is used with low speed or heavy load bearings.

Canadian manufactures babbitt bearings up to 84" outside diameter and lengths up to 64" with a maximum weight of 7 tons. They may be centrifugally cast with any grade of A.S.T.M. virgin babbitts. Manufacturing is done to OEM specifications, and re-conditioning services are offered. Products are used for hydraulic, steam, turbines, gas, compressors, gear drives, electric motors, pumps and more.

St. Louis Bearing specializes in babbitt and bronze bearings. They manufacture both standard and custom types in quantities anywhere from one to long-run OEM. Centrifugal casting from 2" to 36" in diameter and 2" to 72" in length, and static casting up to 8 feet in diameter are available. Applications include oil refineries, steel mills, and many others.

Wheeler Industries designs and manufactures babbitt lined bearings, including journal and thrust types. Other sleeve bearing materials are also offered. Products are used in large motors, high-speed compressors, turbines and generators. Bronze products, high speed and replacement bearings are also available.

American Power Service provides babbitt bearing repair and manufacturing. Applications include motors, pumps, turbines, generators, fans, and all types of rotating equipment. In the re-conditioning process products can be re-engineered to design specifications. Tin and lead based babbitted products are available.

CMT specializes in babbitt bearings for all heavy industrial machinery. They can provide centrifugal casting of all sizes, as well as static cast, metalizing or TIG welding processes. Repair is available. ASTM B23-49 Grade 2 tin-based metals are used.

Magnolia manufactures bearing bronze and babbitt metals. Grade II babbitt is standard and special alloys are available upon request. Magnolia's centrifugal cast machine is capable of spinning 3"-24" diameter bore, with a maximum length of 26". Capabilities include keyways, oil grooves, bronze castings and alloys, and semi-finished and finished bronze.

Milwaukee manufactures babbitt lined bearings. Offerings include halfshell, split journal and segmented types. Centrifugally casting of bearings up to 54" diameter are available. Alloys are cast on the outside diameter, inside diameter or both surfaces if required. Tolerances to .0005" (.0127mm) are maintained.
